Mature and complex are the buzzwords for this split 12" between the now-defunct American punk outfit Libyan Hit Squad and Round Eye, the adventurous Shanghai rabble-rousers that rose from the Orlando-based band's ashes.

The A-side sees Libyan Hit Squad firmly planting themselves in established wild-eyed punk soil ("Blown Asshole," "Rubber Shoes") before pulling up stakes and expanding to more untamed, fertile ground with intricate, layered and mature work. "Full Circle," a five-minute instrumental featuring pure guitar manna from Black Flag mastermind Greg Ginn, is the peak and segues to the ascendant "Brave New World" before an explosive culmination: "Lift Your Knees," a discordant, soaring take on sexual politics.

On the flipside, Round Eye have nailed together a series of disparate sonic elements—supercharged sax-fueled rock and roll ("Round Eye," "Carne Seca"), demented doo-wop harmonies ("I'm So Young") and standard issue post-punk ("Kenting", "Got Her Runnin'")—alongside a boundless cache of thematic influences to present a mercurial five-song exhibit that recreates contemporary China in its own image: a shambling, contradictory and often-wacky work that somehow manages to rein itself back before tumbling off the precipice.

"We're a rock and roll band that's trying to make the rock sax and love songs cool again with a spoonful of sugar," said Round Eye mastermind Chachy during a recent interview. "We try to keep our shows as fun as possible: I once covered the entire audience with flour and threw my guitar at someone to play whatever he liked. We're here to make sure you have something ringing in your skull by night's end—whether it's tinnitus or a tune with a drunken smile on your face, it's time to get weird!"
